The Siemens SIRIUS 3RH1131-1AP00-0TK0 is a size S00 auxiliary contactor with three normally-open instantaneous contacts and a 24 VDC coil rated at 10 A.
Three instantaneous NO contacts handle switching at 24 VDC up to 10 A, with lower ratings at higher voltages — 1 A at 110 V, 0.27 A at 220 V. The contacts are rated for 30 million mechanical operations typical, with a contact reliability of one incorrect switching per 100 million operations at 17 V, 1 mA. Surge voltage resistance is 6 kV, pollution degree 3, so it's suited for industrial environments with moderate conductive contamination.
Wire termination accepts solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². Operating temperature range is -25 to +60 °C; storage and transport from -55 to +80 °C. Shock resistance is 10g at 5 ms and 5g at 10 ms. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward.
